The LCM of 647,814,225,455 is 10783322550.

Find LCM of 647,814,225,455 with Prime Factorization


5 647, 814, 225, 455
647, 814, 45, 91

Multiply the prime numbers at the bottom and the left side.

5 x 647 x 814 x 45 x 91 = 10783322550

Therefore, the lowest common multiple of 647,814,225,455 is 10783322550.

LCM Formula to Find Lowest Common Multiple of 647,814,225,455

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

647 x 814 x 225 x 455 = 53916612750

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

647 : 1, 647

814 : 1, 2, 11, 22, 37, 74, 407, 814

225 : 1, 3, 5, 9, 15, 25, 45, 75, 225

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,814,225,455, is 1.

Now, the common factors can be found like this.

647:647

814:2x 11x 37

225:3x 3x 5x 5

455:5x 7x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

5 = 5

Therefore, the value for common factors is 5.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 53916612750/(1x5)

LCM = 53916612750/5

LCM = 10783322550

Thus, we can understand that the LCM of 647,814,225,455 is 10783322550.
